COMBINEDWASHING AND WRINGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 228,239, dated June 1,1880.

Application filed December 29, 1879. 4

To all whom it may concern Be it known that I, CHAS. H. WOOD, ofChicago, Illinois, have invented a new and useful Improvement inCombined Washing and VVringing Machines, of which the following is aspecification.

The invention relates to a rubbing attachment for clothes-wringers.

It consists, principally, in combining with the rolls of aclothes-wringer rubbers which are supported upon swinging arms orsprings and pressed toward the wringer-rolls with a yielding pressure,while an oscillating reciproeating motion is given to the rubbers by thedriving mechanism, in the manner and for the purpose substantially ashereinafter set forth.

It consists, further, in the means employed to hold the rubberstogether.

It consists, further, in the means employed for holding the rubbersapart when they are in motion.

In the drawings, Figure l is an elevation of one side of my machine.Fig. 2 is a view of the washer side of my machine separated from thebox; and Figs. 8, 4, and 5 are full-size detail drawings of the rubbersa a, when made of malleable iron, for a full-size machine. Fig. 6 is aperspective view, showing how the yokes 0 and p are loosely heldtogether.

The clothes wringer is made in the usual manner, except that the sideposts, D, are extended above the wringer proper to receive and supportthe shafting and springs of the washing attachment, and the posts areconnected by a cross-bar, B, at the top.

The cross-bar A (shown in Fig.1 only) is the top of the wringer proper,and E represents the pressure-spring of the wringer-rolls.

Upon the side posts, D, and above the wringer proper, are properlysecured two long springs, b, which extend downward, so that their lowerends are opposite the rolls of the wringer, and a pin, a, is attached tothe lower end of each spring, to form pivots for the rubbers a a tooscillate upon. By these means the rubbers -are supported in positionand pressed against the rolls of the wringer with a pressure which mayberegulated by the bolt and thumb-screw d, as shown in Fig. 1.

For convenience in making the model, the rubbers are made of wood andarms of sheet metal are attached to the ends of the rubbers; but for afull-size machine the rubbers and the arms may be made of malleable ironand cast in one piece.

Figs. 3, 4, and 5 are full-size detail drawings for the rubbers, 'whenmade of malleable iron, for a full-size machine; but the size, shape,and material of the rubbers may be varied as desired.

The rubbing-face is fluted likea wash-board, and is intended to operatelike a wash-board precisely, except in this respect, that the ordinarywash-board is held stationary and the clothes are moved back and forthover it, while in my machine the clothing is held stationary by therolls of the Wringer and the rubbers are oscillated back and forth whilepressed against the clothing or the rollers by the springs b b, thusproducing the same action upon the clothing as rubbing between thehands.

It will be understood that the clothing is passed through or between therubbers, and then between the rolls 0 c, the rubbing being done betweenthe rubbers a and the rolls 0, which hold the clothing stationary, and,being turned as fast as may be desired, draw the clothing along andbring a new part under the action of the rubbers.

The rubbers a a are oscillated by the yokepitman p, the lower part (yokep) being connected to the lower rubber, and the upper end beingconnected to the crank or eccentric n of shaft 1. This shaft isjournaled in boxes in or upon the side posts, D, of the wringer. Theshaft I has a balance-wheel, h, and a pinion, i, which meshes with wheel0, and the latter turns upon a stud, t, which is properly secured to theside post, D. The wheel a has a straight round stud, f, to receive apitman, 12, so as to be operated with the treadle 10.

When it is desired to turn the machine with the hand the crank g isproperly secured to the stud f, and may be detached when the machine isoperated with the foot.

The extreme ends of the horizontal part of yoke 0 are forked, so as tostraddle the upright parts of yoke 12, as shown in Fig.6. Thus the yoke0 is free to move up and down, but lateral motion is prevented, exceptas the two yokes move together. The lower ends of the yokes areconnected to the rubbers by pins, as shown and the spring 2 forces thetwo horizontal members of the yokes apart, so a-s to hold the tworubbers together.

In the model the parts 1) and p are made of separate pieces; but for afull-size machine I prefer to make them of malleable iron and in onepiece, as shown in the drawings.

The two rubbers may be opened or held apart when they are in motion bypulling upon the straps or cords 2, attached to the yoke 0, and passingup over pulleys 3 3, which are loose upon shaft 1, or otherwise properlysupported in proper position, and are retained in convenient position soas to be grasped by the hand when it is desired to open the rubbers soas to start in a new piece of clothing into the rollers c 0 withoutstopping.

The wringer-rolls are turned automatically by the treadle to operatingpitman 4, which has a spring-pawl, 5, near its upper end, so as toengage with the ratchet-wheel 6, which is fast upon the shaft of one ofthe rolls 0. The arm 7 is loosely secured on the shaft of theratchet-wheel and connected to pitman 4, so as to hold the latterimposition and cause the pawl 5 to remain in contact with wheel 6,except when the movable shield 8 holds the pawl ofi" from the teeth.

The shield 8 is loose on the shaft of wheel 6, and may be turned aroundso as to cover such teeth on the face of the ratchet-wheel as A may bedesired, so that the pawl may be in crank it, which is fast upon theshaft of the wheel 6.

One office of the springs b is to support the rubbers so as to allowthem to move to or from the rolls, to adapt themselves to the vary ingthicknesses of the clothing, and yet have but little or no verticalmotion. This would be accomplished as well if the parts I) were madestraight and rigid their entire length, except being jointed near theshaft 1 or at their upper ends.

Another oflice of the swing-arms b is to give an elastic pressure of therubbers against the wringer-rolls. If the parts I) were rigid andjointed, as just mentioned, a yielding spring would be necessary inconnection with the bolts and thumb-screws d. This rigid and jointedform of the arms 71 is only a variation in the construction of themachine; but it may prove to be preferable to the construc tion shown inthe model.

1 claim- 1. The combination of the rolls of a clothes wringer andrubbers pivoted upon swinging arms or springs and adapted, by meanssubstantially as described, to have an oscillating motion, substantiallyas and for the purpose set forth.

2. The combination of the rubbers pivoted upon swinging arms or springswith the yokes 0 and p and spring asubstantially as set forth.

3. The combination of the rubbers, yokes 0 and p, pitman 1), shaft 1,pulleys 3, and cords 2, arranged to operate substantially as described.

4. The combination of the rubbers a, swing arms I), yokes 0 and p,pitman p, and shaft l, all constructed substantially as set forth, andcombined with the rolls of a clothes-wringer.
